Unlike Compatibility, Expected, and Maximum modes, which are literal strings that represent predefined export width definitions, DEFAULT is an SQL keyword that does not have a predefined meaning and is not delimited by SINGLE QUOTATION MARK characters.
If you specify DEFAULT as the Export Width for a user, Vantage assigns the export definition that is currently defined in the Export Width Table ID parameter of DBS Control to that user. For more information, see Teradata Vantage™ - Database Utilities , B035-1102 .
